HUB FOR CARRIAGES.

Specification of Iietters PatentiNo. 14,294, dated February 19,1856.`

To' aZZ 'wh/0m z' may concern i Be it known that I, JOSEPH SMITH, ofSunbury, in the county of Delaware and State of Ohio, have invented anImprovement in I-Iubs for Carriages, &c., and that the following is afull, clear, and exact description of the principle or character whichdistinguishes it from all other things before known and the usual mannero-f making, modifying, and using the same, reference being had to theannexed drawings, of which- Figure l represents a transverse sectionthrough the hub box wheel and axle. Fig. 2 a perspective view showingthe interior. of the hub box by the segmental piece c being. removed.Fig. 3 a perspective of the segment c. Fig. l a different shaped hubalthough of the same principle.

My invent-ion consists in a peculiar arrangement of the hub for axletrees of carriages, etc., by which I accomplish the very desirable andindispensable necessities, in order to obtain a perfect, practicable,cheap, compast easily of draft and safe reliable hub.

The object by which I have acquired this complete device has been solelyfrom study and experience on. this subject, and'this yI have attained aswill be clearly seen by close observance of the following description. Ihave rendered this hub simple compact and light and at the same timeapplicable to all varieties of conveyance. I avoid the extended portionof the hub which projects from the face of the wheel outward and whichis liable to cause very serious accidents, by one wheel coming incontact with another on the thoroughfare. I obviate to a very greatextent the friction produced on the axle which necessarily produces anunnecessary amount of draft on the team; and I give strength to the axleat the point of contact with the hub, rather than hcw it to fit a smallbore in the hub, at the same time giving the wheel the proper pitch, andsecuring it firmly to the hub, and the hub to the axle. I also renderthe interior of the hub very accessible and prevent the running oif ofthe wheel, and a mechanic can fit the axle which is perfectly straightto the hub with great ease 'without the necessity of giving it theperfect taper which, to give the wheel the proper balance on the axle isabsolutelynecessary in the common form of hub.` l

vTo the axle tree a, and secured firmly thereon by a bolt b is a hub boxc, this box is composed of cast iron, and formed of two parts c, c asshown in Fig. l. The segment cl is made detachable for the purpose yofsetting in the slotted cylinder Z into which the spokes c-e aremortised. This cylinder a7, is made also of cast iron and has an annularslot f castin it for the purpose of allowing the rim g on the box c toenter, thereby forming a flange for the purpose of securlng the cylinderd in its proper place. This cylinder is hollowed out as seen at ZL Fig.l

so as to avoid unnecesary weight and the same time to give it thesufficient strength required. A space is left between the rim andthebottom of the slot f in the cylinder Z for the reception of frictionrollers i flete. shown in Figs. 1 and 2. These rollers entirely lill upthis space le-ft for them and allow the wheel from motion. In additionto the bolt for securing the parts c c of the hub box together I bracethem, by the employment of a band lc which also serves-to tighten theparts if they wear loose. The lugs Z Z lit into recesses Z Z for thepurpose of setting the segment in its proper place while placing in thebolt o. 'Ihe desired cast of the wheel is given by casting the hole forthe reception of the axle out of a true line wit-h the hub as clearlyshown in Fig. l. I have contemplated using different sizes for differentvehicles without altering the nature of my invention. One form is shownin Fig. 4L for heavier vehiclesand necessarily the parts are much largerand stronger than the one above described which is for light carriages.

I am aware that friction rollers have been used for relieving thefriction on the hubs of vehicles and this I do not claim but- What I doclaim and desire to secure by Letters Patent is- The combination withthe axle of vehicles of a segmental box c c', slotted cylinder d andfriction rollers z', z', all arranged and operated as substantiallyabove set forth.
